This study attempts to classify the children with intellectual disabilities using two speech feature extraction techniques: Linear Predictive Coding (LPC) based cepstral parameters, and Mel-frequency cepstral coefficients (MFCC). Four different classification models: k-nearest neighbour (k-NN), support vector machine (SVM), linear discriminant analysis (LDA) and radial basis function neural network (RBFNN) are employed for classification purposes. 48 speech samples of each group are taken for analysis, from subjects with a similar age and socio-economic background. The effect of the different frame length with the number of filterbanks in the MFCC and different frame length with the order in the LPC is also examined for better accuracy. The experimental outcomes show that the projected technique can be used to help speech pathologists in estimating intellectual disability at early ages.<\/jats:p>","DOI":"10.4018\/ijcini.2020040102","type":"journal-article","created":{"date-parts":[[2020,2,28]],"date-time":"2020-02-28T07:51:44Z","timestamp":1582876304000},"page":"16-34","source":"Crossref","is-referenced-by-count":12,"title":["Comparisons of Speech Parameterisation Techniques for Classification of Intellectual Disability Using Machine Learning"],"prefix":"10.4018","volume":"14","author":[{"given":"Gaurav","family":"Aggarwal","sequence":"first","affiliation":[{"name":"Manipal University Jaipur, Jaipur, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Latika","family":"Singh","sequence":"additional","affiliation":[{"name":"Ansal University, Gurgaon, India"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"2432","reference":[{"key":"IJCINI.2020040102-0","first-page":"88","article-title":"Involvement of adolescents with intellectual disabilities in social and recreational activities.","volume":"14","author":"D.Abells","year":"2008","journal-title":"Journal on Developmental Disabilities"},{"key":"IJCINI.2020040102-1","doi-asserted-by":"publisher","DOI":"10.1080\/1206212X.2018.1475330"},{"key":"IJCINI.2020040102-2","doi-asserted-by":"publisher","DOI":"10.1016\/j.eswa.2011.07.065"},{"key":"IJCINI.2020040102-3","doi-asserted-by":"publisher","DOI":"10.1007\/978-3-642-14209-3_9"},{"key":"IJCINI.2020040102-4","doi-asserted-by":"publisher","DOI":"10.1044\/1092-4388(2012\/11-0257)"},{"key":"IJCINI.2020040102-5","article-title":"Maternal speech to prelinguistic children with Down syndrome.","author":"C.Cardoso-Martins","year":"1985","journal-title":"American Journal of Mental Deficiency"},{"key":"IJCINI.2020040102-6","first-page":"1","author":"A.Cutler","year":"2005","journal-title":"The cornerstones of twenty-first century psycholinguistics.
